NOTE ON UPDATES
Azuirele has decided to retire from modding ATS: https://forum.scssoft.com/viewtopic.php?p=2123105#p2123105

The mod should still work until version 1.60, but support has ended with version 1.61.
-----

Welcome to US Car Culture, a mod I’ve been developing over the past few days to enhance realism in American Truck Simulator. This mod is designed for players who, like me, want more realism in their gameplay.

GAME VERSION SUPPORTED
🟡 ATS v1.56.* and below : Legacy Support only, please update your game to use my mod to its fullest.
✅ ATS v1.57.* : Partial Support (Latest mod version: v2.9-1.57-5)
✅ ATS v1.58.* : Official Support (Latest mod version: v2.9-1.58-7)
✅ ATS v1.59.* and later: Unofficial Support (Latest mod version: v2.9-1.59)
To understand what each support status means, you can read about them here[forum.scssoft.com].

LOAD ORDER & COMPATIBILITY
General load order of all US Car Culture content:
1. US Car Culture - Compatibility Patch.
2. US Car Culture - AI Pack's addon.
3. US Car Culture.

Load order with other mods:
⬆️ Above any realistic traffic/traffic density mods.
⬆️ Above any non-supported AI Traffic pack.
⬆️ Above any map mods.
For other mod categories that are not mentioned here, you can follow the general load order for mods.

Known Incompatible mods:
❌ Any realistic AI vehicle color mods, as this feature is already included in my mod.
Besides that, my mod also modifies the following game files:
  • Most of /def/vehicle/ai/<vehicle>.sui
  • Most of /def/vehicle/traffic_storage.sii
  • /def/country/traffic.sii
  • /def/country/license_plates.sii
  • Some AI models/model LODs files
If another mod only modifies one of these files (not all), load it below my mod to ensure partial compatibility.

Please make sure to follow this load order and requirement strictly, to ensure my mods function properly, and prevent any unusual behavior in your game. Specific mods are also fully supported individually by US Car Culture, and are listed in OTHER MODS COMPATIBILITY STATUS

KEY FEATURE
🚗 Realistic State Traffic
➜ Reworked all AI vehicle brands' spawn rate based on their market share in the US.
➜ Reworked all AI vehicle types' spawn rate based on their market share in each US state.
➜ Reworked each AI spawn rate individually.
➜ AI vehicles that are not marketed in US will no longer spawn, including in traffic, road events, parking lots, etc.
➜ AI Classic/Antique vehicles' spawn rate has been significantly reduced to reflect their rarity.
➜ Rare variants of AI vehicles, such as Ford F-150 Raptor, will also spawn less.
➜ Old-generation AI vehicles will also spawn less.

⏲ Vehicle specs improvement
➜ Adjust vehicle specs, such as engine power/weight ratio, using data from Auto-Data.net and Wikipedia.
➜Fixes/corrected numerous wrong spec numbers from SCS.
➜Additional condition for certain AIs.
➜Additional tags for every AI that doesn't have.

🟥 Color Expansion (REQUIRE ATS v1.57 ABOVE)
➜ Colors for vehicles are based on their actual colors that are or were offered during their production, available to be found on PaintRef.com.
➜ Color varieties are based on the era they were produced in; the older the era, the more colorful they would be.
➜ Color varieties are also based on body style. For example, pickup trucks will slightly have more white color than others.
➜ Sport/Muscles class or Classic/Antique vehicle will have its own unique color profiles, completely stand out from modern-day color preferences.

🪪 License Plate Expansion (REQUIRE ATS v1.57 ABOVE)
This is currently the latest feature of US Car Culture, added after v2.0.
➜ Add more plate designs to each US state.
➜ Among different designs, currently features the following license plate types:
  • Standardized license plate, including all common series and historic series.
  • Specialty license plate, including charity variants and region-specific variants.
  • Other types, such as veteran, disabled person, or state-specific license plate.
➜ All license plates have near-accurate series formats and font color, including non-passenger vehicles. (Due to game limitations, a perfect resemblance is impossible at the moment)
➜ Introduce out-of-state vehicles, now you can actually see vehicles from different states cruising on the interstate, or simply visit the city area.

➕More AI variants (REQUIRED ATS v1.57 ABOVE)
➜ Add/enable unused or incomplete AI created by SCS
➜ Add more trailer variants for some AI, aiming to improve the diversity in traffic.
➜ From v2.9, add more AI from ETS2 that are/were marketed in US.
If you are curious to know, all the new AIs from my mods are listed in here.

I found a small problem in the state of Arizona; the letters on license plates appear enormous there. It's the only state where I've seen this issue.

@Dragon32 Yeah yeah I have the mods needed to run the patches.

Like I said its not all the vehicules that dont have audio, its some of them. Some of them are dead quiet, no audio. So I was thinking maybe its a patch that needs updating. Idk. Its not the end of the world. Its playable. Its just something I noticed.

OK, well if you're only using the patch mods you need for the mods you're running, and aren't running more patch mods than you need. And all of those are in the right order... then I don't know what's going on.

I'm using the three "AI pack add-ons" and the "Sound Fixes - Drive Safely" compatibility add-on without a problem.
